YONHAN Battery Charger 10-Amp 12V and 24V Fully-Automatic Smart Car Battery Charger, Battery Maintainer Trickle Charger, and Battery Desulfator with Temperature Compensation

This is a nice little charger, great for the price. This is simple to use, works well and afordabe. The wires are a little cheap, but for what it is, its great. I have it connected to a 12v lead acid that runs my well pump (6a 12v) and it works great. I connected it and have to do nothing now. Great purchase!

This little thing works great! My car battery was dead this morning. Ordered it and received it within hours same day. Only charged less than 10 minutes and car started with no problem. It's small enough to keep in my trunk just in case I need it again in the future.

This worked so well I had to come write a review. It charges really fast. Love that it displays your battery percentage as well. Went from 40% to 100 in about an hour and a half. Most other 10 amp chargers were $60 to $100. This thing's an amazing value

Much smaller and lighter weight than I was expecting. The charging system is fully automatic which is nice. I only wish that both the battery cables and the plug in cord were longer so I wouldn’t have to use an extension cord every time.

I have purchased several of these chargers so that I can basically leave them as trickle chargers on a couple of my vehicle batteries. They are quick and easy to connect properly and do a very good job of bring your batteries up to their full potential. Understand that you cannot charge a completely dead battery. There must at least a small amount of juice left in the battery for the charger to start its programming. It's been about a year and a half since I bought my first one of these. It has continued to function very well so I'd say the quality and dependability are great with these chargers. So I recommend them if you want a quick and easy to use charger for your vehicle batteries.

This thing is awesome I saw the smoking video and went a head and got it anyways. I had two motorcycles batteries that would not hold a charge now they do. I had a dead truck battery would not hold a charge. Yep NOW THEY DO . It does take more time to charge than my old 100.00 one but I am okay with that . Price is great the product does work great . It CAME ON TIME YEP .

My 6-year-old Audi Q5 can start OK, because it has a strong starter (has auto start/off) but because of it's low state of charge, that function no longer works. I bought a trickle charger before this one which charged well on a 2019 Corolla that's being driven very little and infrequent but not on my 2018 Audi Q5. That other trickle charger charged my battery from 11.7 to 11.9V. I bought this charger due to it has a separate mode for AGM and Repair because my Audi battery is AGM. FYI, manual says you need to wait at least an hour from the last usage of your battery. So, I first charged it in the AGM mode and the display went from 50% to 100% in only 10 minutes but the voltage only improved to 12V. Yesterday I put it on repair mode, and it took 8 hours to show full. I did not wait for it to turn off by itself. The battery now has improved from 12V to 12.55V; from 50% to 80% capacity on a 6-year-old large AGM battery. I did not bother to remove the power cords due to my bad back and the battery is situated in the trunk all the way behind the backseat. Luckily it does not appear to cause any damage to my car. During the repair mode, I monitored the battery temperature with my laser thermometer; the charger nor the battery did not get warm and stayed in the low 70's. PROS: 1) Has separate AGM and Motorcycle and repair mode. 2) Great LCD lighted display will show the battery level when you hook it up even before you plug in the power cord. It will also show charger temperature, charging current & status, battery voltage & etc. 3) Smart charger has a built-in fan to stay cool and it will alter the charging power with respect to the battery status. It will start out slow and rarely goes to the full 10A, then it will decrease the power when you reached half full then even lower at 75%. Even when it's @100% charged, it will trickle charge to the max then turn itself off (fan off but light still on) and display OFF. 4) Great repair mode that reconditioned my 6 year old AGM battery from 50% to 80% capacity. 5) Very good price; I paid $24 shipped. CONS: 1) Very short cord, you will need an extension cord. But it's no big deal. 2) Per owner's manual, in Motorcycle mode, it will charge battery to full then turn off and turn back on when voltage drops below 12.5V. But does that mean you cannot maintain your battery in the other modes? It also states not to leave the charger unattended over 12 hours. Therefore, I don't think this is a battery maintainer which is fine for me. ................................................................ With this battery charger, I can charge my batteries before and after I go on a vacation and let not my batteries charge level go down too low thus prolongs the life of my batteries. I only had it for a week and so far, I am very happy about this product. I will update if the charger quit or have some problems.

Worked great charged my battery very well. Nice and compact.

A great charger at a great price.

Easy to use

Needed a battery charger to help restore a car battery that was really low. Saw so many different options and pricing for models that I didn't know where to even start. Then I saw how many people bought this little charger and raved about it. For less than $40, why not give it a go? So happy I did. This charger is amazing. Plug and play and so simple to use. Took a few hours but got my battery back to 100% with the bonus repair function built right in. Have used it to repair and top up other batteries as well. Totally satisfied and already recommended it to a buddy to buy and he is loving it as well. Great purchase!
